Recommend me some software

[icelag]

Hello I need some recommendations and advice for running a user-friendly software for a small business.

Basically, I've got a bunch of suppliers, bunch of customers, bunch of products and a bunch of orders. The latter takes data from the 3 'bunches' before it. New products are added on everyday. I need a computer program that can organise all this data (including photos for the Products list) on a computer network AND be viewable on a smartphone. I'm open to any software and any smartphone.

Thank you.
